' HEATING PLANT.

State of Maine, have invented certain new" and useful of which the following is a specification.

' This invention relates to heating plants and has for an object to provide a device for employing .fluid fuel with "improved means for volatilizing, oxidating and igniting the fuel. l,

A further object of the invention is to provide an improved form ofburner for adimltting and igniting the gaseous product volatilization.

- Further object of the invention is to provide a retort positioned in improved location relative to the burners whereby a more com plete and attenuated volatilization is accomplished. r With these and other objects in vieiri the invention comprises certain novel units, parts, elements, combinations and arrangements as will be hereinafter more fully described and claimed. c

Referring to the accompanying drawing which is made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a view of the improved heating diagrammatically shown in side elevation with parts broken away to show the internal. construction,

Fig. 2 atop plan view of the burner area, and Fig. 3 a vertical, diametrical, sectional I view through one of the burner units.

The improved heating plant, which forms the subject matter of this application, comprises a base 10 supported in any approved manner, but preferably by a support 11 in the form of a housing'or casing. Into the housing or casing 11 a pipe 12 is inserted having a funnel or hopperlike upper extremity 13 corresponding substantially with the burner area defined by the marginal wall fan blower 15 operated in any approved manner, as by an electric motor, conventionally shown at 16.v The base 10 is properly drilled and tapped to receive a plurality of burner units 17 preferably arranged in rows, as indicated at Fig. 2. The arrangement of the burner unlts Specification of Letters Patent. I I Application filed June 12, 1920. Serial No.

- the base 10.

.and'28 will cross, as at 29.

Communicating with the pipe 12 is a .the medium of the valve cup 32 is attached by the link 34, such link Patented Nov.29, 1921. 388,512.

in this form permits\the retort coil 18 to take the form of a spiral having nearly square turns at the several corners with the outlet extremity at 19 directed downwardly substantially through the center of the Improvements in Heating Plants,

base 10. Y

\ Go mmunicating with the retort 18 is a Where the extremity of the retort is inserted through the base 10 as at 19 it is provided with a perforated section 24 from and again e position of l wh1chthe gaseous product of volatilization in the retort 1s discharged laterally into the hopper 13 where it commingles with the air produced by the fan blower 15 and is thereby forced upwardly through the burner units.

Each of the several burner units comprises a substantially spherical head 25 (see Fig. 3) which for-convenience will be' provided with a multiangular lug 26'which permits the application of a wrench thereto for insertion of the burner into and removal from The spherical head 25 of the burner unit is stantially equatorial perforations 27 and a series of perforations 28 located above the perforations 27 and directed downwardly so that the discharge from-the It is desirable 1130 provide the plant with automatic means'for shutting off the fuel and current to the fanl motor in case of failure and in communlcation with a pipe 31 which leads to and discharges into a drip cup, 32. The latter controls the fuel supply'through 33 to which the drlp belng also connected with the switch 35 which is positioned in the circuit, indicated at 36. en, by reason of discharge of fluid fuel through the perforated section 24,

provided with a series of subperforations 27 I the structure just described causes the fuel to flow into the drip cup 32 and by applying the weight of such fuel causes the drip cup to fall closing the valve 33 and opening the switch 35 whereby the flow of fuel is discontinued and current to the motor is interd rupted.

It is believed. that the operation of the plant will be thoroughly and completely understood from the foregoing without further statement specifically directed tov the operation. Having thus fully described my said 1nvention what I claim as new and desire to secure by Letters Patent, is:
